After the device has given up the ghost after about 8 months, was the question of a complaint in the room. After what felt like 10 emails was understood until finally, what's the problem, it said: proof reversal, I should look for a expert. So I have been unlucky. The device worked well at first, later went with the lowest load nothing (despite full battery ...). The dealer did not understand that a complaint has the best chance to inspire a customer. I'm serious. Can sell at any but to help a customer if he has a problem that I have the art, or the chance. No sign of sustainability. Unless, you want to lose customers. That has succeeded, and I hope more customers to sensitize it better to go to specialist shops locally to do here, at least in this company an arc. AM
